</div><pre style="font-family: monospace,monospace; white-space: pre-wrap;">Introduce PCUIF, BTS and ClckGen components for RAW PCU test cases<br><br>The problem of existing test cases is that they mix IUT (i.e. OsmoPCU)<br>with OsmoBTS (osmo-bts-virtual) and OsmocomBB (virt_phy). This approach<br>allows to avoid dealing with TDMA clock indications and RTS requests on<br>the PCU interface - this is done by OsmoBTS. On the other hand, our test<br>scenarios may be potentially affected by undiscovered bugs in OsmoBTS<br>and the virt_phy.<br><br>In order to solve that problem, this change introduces a set of new<br>components and the corresponding handler functions:<br><br> - RAW_PCUIF_CT / f_PCUIF_CT_handler() - PCU interface (UNIX domain socket)<br> handler. Creates a server listening for incoming connections on a given<br> 'pcu_sock_path', handles connection establishment and message forwarding<br> between connected BTS components (see below) and OsmoPCU.<br><br> - RAW_PCU_BTS_CT / f_BTS_CT_handler() - represents a single BTS entity,<br> connected to OsmoPCU through the RAW_PCUIF_CT. Takes care about sending<br> System Information 13 to OsmoPCU, forwarding TDMA clock indications from<br> a dedicated ClckGen component (see below), and filtering the received<br> messages by the BTS number. Implements minimalistic scheduler for both<br> DATA.ind and RTS.req messages, so they are send in accordance with the<br> current TDMA frame number.<br><br> - RAW_PCU_ClckGen_CT / f_ClckGen_CT_handler() - TDMA frame clock counter<br> built on top of a timer. Sends clock indications to the BTS component.<br><br>All components communicate using TTCN-3 ports and explicitly defined sets<br>of messages (see RAW_PCU_MSG_PT). One noticeable kind of such messages is<br>events (see RAW_PCU_Event and RAW_PCU_EventType). That's how e.g. the PCUIF<br>component can notify the BTS component that OsmoPCU has just connected, or<br>the BTS component can notify the MTC that SI13 negotiation is completed.<br>Events may optionally have parameters (e.g. frame-number for TDMA_EV_*).<br><br>Furthermore, the proposed set of components allows to have more than one<br>BTS entity, so we can also test multi-BTS operation in the future.<br><br> +-----+ +----------+ +---------+<br> | MTC +---------------+ PCUIF_CT +------+ OsmoPCU |<br> +--+--+ +----+-----+ +---------+<br> | |<br> | |<br> | |<br> | +-----------+ |
